To a chlore t may concern.-

Be it known that l, ALPHONSE Simmer, citizen of the United States, residing at Albuquerque, in the county of. Bernalillo' and Stateof New Mexico, have invented new and useful Improvements in Nail-Drivers, of which the following is a specification.

My present invention pertains to means for holding anddriving nails andthe like; and it has for its general object to provide -a simple, compact and durable device designed more especially for facilitating the nailing of soles'v on shoes and constructed with a view vtovcontaining a number of nails in a magazine, supplying the nails one by one-in proper fashionand in proper positionto a holder, and displacing the nails ne by one from said holder and driving the nails.' Theinvention in all. of its details will be fully understood from the following de-v scription and claim when the same are. read 'in connection with the drawings, accompanying andforniing part of thisspecication, in which: Figure lis an elevation of 'my .novel device. Fig. 2 is aview, partly in diametrical section and partly in elevation., of the same. Fig. 3 is a View, partly in section and artly in elevation, talren at a right angle to Igig. 2. Figsl and 5 are detailed views hereinafter specifically referred to.

Similar numerals of-reference designate corresponding parts in all of the views of the draw-ings.v

Among other elements 'mynoveldevice comprises a cylindrical casing section 1, that is reduced and exteriorly threaded at its opf posite ends for the connection of an apertured cap 2 and a lower casing member 3; the exterior of the said cap 2 and the eXterior of the said member 3 beingfpreferably rougheneai' as shown in Fig. l, to render easy turning of the sam-e on and ott the sec* tion 1. I

Mounted and adapted to rotate at one side of the member 3 and extending belour the saine is a toothed wheel 4t. The teeth of the said wheelffft are arranged at a distance apart corresponding to the distance at which the nails are to be placed apart, and when the operator in pushing the device with his' hand in vwhich the same is held feels one ot the teeth of the wheel -t engage the leather, the operator is apprised of the fact that he position the nails apart.

Connected by a conventional screw 5,a thumb-screw or any other suitable means to the lower end of the. member 3 is a gage 6. The said gage 6 is longitudinally slotted for the passage of the shank of the screw 5, and is designed to enable the operator of the device to position the nails at a distance de sired from the outer edge of. the sole that is to be nailed to a shoe vamp.

Suitably fixed with respect to the casing section l is a magazine 7 designed to contain the nails to be driven. The said ,lagazine vhas abottome Wall 8 which is pitched or inclined downward toward thesaid casing section. l, and is provided, in turn, with a slot' 9 designed to receive the nails after the nianv ner shown in Fig. 3, and support lthe nails by the heads thereof; the said heads being larger than theslot 9 is Wide. ln communication with the slot 9 in the bottom of magazine '.7 is a vertical slot 10 in the wall of the cylinder section L Fixed by a screw l1 or other suitablemeans in the cylinder section l is a metallic provided with a vertical central bore 13, and guidedV in the said bore and in the central aperture of the cap 2 is thereciprocatory nail-driving plunger 14. Said plunger is of metal, and is preferably, though4 not necessarily, provided with a head 15, of leather o r analogous material, designed to receive the blows .of a hammer ormallet.- At an intermediate point of its length the plungerl is provided with an Ienlargement 16, de signed tobring up against the cap 2 and limit theA upward movement of the plunger, and immediately below the said enlargement `l6 the Iplunger is provided with a -lateral ,upwardly tapered portion 17, best shown in y Figs. 2 and'B. 'At a slight distance below the tapered portion 17 vthe plunger has an abutment 1 8, and between the said abutment is interposed a coiled spring 20, having for its function to return the plunger to and yieldingly retain the sante in tlfe normal po' sition shown in Figs. 2 to 4.

OpposedA to eachi other and arranged in has moved the device far enough to properly core l2, Figs. 2, 3 and at. The said core is and the bottom of a soclret 19 in the core 12' denominated the vertical center of the casing` member 3 y are nail-receiving and holding' ifzws 21. The f said jaws are provided in their outer sides g with shallow sockets 22, which sockets are disposed l l above and below the horizontali center ot the jaws` and are designed'to rc l ccive coiled springs 23,- which are arranged ,l between the jaws and the` wall of the meml ber 8, and have their outer ends maintained l 'in position by .screws 24bearing in the]i member 3. By virtue otsaid construction it will be manifest that the jaws are adaptl ed to receive a nail that gravitates to a posif tion within them, and are also adapted to I hold the saidA nail in the verticalcenter of I the device andihence in vertical alinement i with the plunger let. It will further bei manifest that when the plunger is impelled downward, the jaws will give outwardlyl and will consequently enable the plungerl to properly drive a nail home into and; through a shoe sole or other article that is `to be nailed to another article. I Formed in the core l2 is a nail passage the lower end ot' which is disposed above and adapted to discharge nails into thel space between the jaws. At its upper end l the said passage 25 merges into a vertical passage 26 formed in the side of the core I and having its upper portion increased in I width and arranged opposite the slot l0 in the casing section 1, as shown by dotted l lines in Fig. 5.

Suitably guided in the casing. section l and the core l2 is a rectilinearly and hori- '/,ontallyl movable separator 2T which is so because it has tor its function to assure the nails passing one byA one from the bottom of the magazine andthrough the slot 10 and ,the passages 2G and 25. The said .separator 27 is returned to and yieldingly retained in the position shown by a spring plate 28, lixedly connected at one end to the outside of the casing section l, and bearing at its opposite end against pne end of the separator. lt will also bev 'observed that the separator is provided with a lateral arm 29 that-is opposed to the tapered portion 17 of the plunger le, and t that the separator is further provided with a nail passage 80; the latter being preferl ably ofthe shape shown in Fig. Ll, andbeing normally held out ot' registration with the coincident slots in the casing section l and the magazine.

ln the practical operation oit myl novel device. the operator grasps the cylinder secl l l l tion l in his lett hand and moves the device l step by step over` the article that is to be nailed. 'When the device properlyl positioned, the operator strikes the head l5y ot the plunger le a sharp blow with a mal! l let, and consequently impels the plunger l 1 l l downward against the action ot the spring v20. VASuch dqvvnward movement of the plunthat in the vcombination ol a gel-will be attended by driving` the nail previously positioned between the jaws 2, and will also be attended by .movement ot the separator 2T under the action ot the spring Q8 so to put the ,passage 30 into registration with the` Slot l0 and enable the lower-most pendent nail of the .series in the j slot S) to enter the vouter portion ofthe passage 30. Subsequent to the described down ward movement ot' the phmger let, the said plunger will be moved upward by expansion ofthe spring 20, and incidental to such upward niovenient, the tapered portion 17 acts against the separator arm 29 and moves the separator QT in the direction indicated by arrow'in Fig. e, and against the action of the spring` with the result that the nail received in ille passage 3021i the separator is separated irom the other nails and is dropped into the upper wide portion of the passage 2C trom. whence passes through the passage and assumes its proper central and upright position within and between the Jaws 2l., ready to .be driven on the succeeding downward movemenbot' the plunger 14.

lt will be gz thered from the foregoing operation ot my novel device the proper feed of the nailsis assured by the shoclcand jar incidental to each blow imposed on the head oit the plungerv le; and it will also be appreciated that the deviceas a whole is simple, compact. andstrong in construction, and hence is well adapted to withstand the rough usage to which devices otl correspondng` vcharacter are ordinarily subjected.
